WARNING:To avoid accidental starting, move
P.T.O. switch t o " O F F p o s i t i o n and turn igni-
tion switch " O F F and remove key.
B. Insert feeler gauge through access slot and
i n t o a i r g a p between armatureand rotor. (Fig.
11) There should be some resistance felt, o n
both sides o f gauge, when clutch/brake is
properly adjusted. Repeat this step in at least
three locations o n clutch/brake. If feeler
gauge cannot be inserted into air gap or gap
is too large, follow procedures below to
adjust.
C. If P.T.O. switch is turned "ON" and attach-
ment does not drive, turn all three locknuts
equally
Y:
turn clockwise. (Fig. 11) T h i s w i l l
decrease air gap and allow clutch surfaces t o
engage. Recheck gaps with feeler gauge, if
more adjustment is required, continue turn-

turn until correct ad-
justment is achieved.
D. If P.T.O. switch is turned "OFF" and attach-
ment does not stop or no resistance is felt in
step"BU, turn all threelocknutsequally % t u r n
counterclockwise. This will incease air gap
and allow clutch surfaces t o disengage. Re-
check gap with feeler gauge, if more adjust-
ment is required, continue turning locknuts
